I am very anal collector and have found that if you have patience and are willing to work hard and ask the right questions you can score some amazing deals if you look around.
For example, I just got a sealed Ninja Turtles 3 (right here in my hands too!) for $13.
A couple months a go I got a sealed Mario Bros. 3 for $20.
And just recently I got a Sealed Zelda A Link to the Past for $11.
Although you cheap asses may not think they are bargain deals I scored a lots of old snes games from collectors. They liked me, so I got a good deal, imo. These include Secret of Mana, Final Fantasy III, Kirby Superstar, Illusion of Gaia, and a few others. These were all immaculate! Nintendo Promos, Registration cards, the infamous Nintendo Power inserts, etc.... I'm happy that is for sure
Screw the new gen crap! Just give me a N64, SNES, and NES and I am set for life.
